I just got my new putter actually same putters in August, Magnets in just a just a new plastic, and then did a quick method of having the plastic at the constancy it would be in a few months of constant play, it gets to a point in flex then stays there for a while I just have to have have the disc rim get worn in now, I still have the old hard plastic Pro D putter pre 2006 that was also stiff. Due to a course I played on vaction I had to get rid of the newer hard Pro D Magnet that plastic was softer on, my approach disc, so I got new Magnet Putters in Jawbraker Plastic.
On vacation at a course in Erie State Park, NY they had a basket that was in my mind too close behind a tree, you had only one side to putt into thick brush with wild roses was on one side while the other side was a cliff so you had to make your shot to the left side of the basket and I hit a tree as my disc landed with the tree in front of the basket I was using my softer hard Pro D Magnet the approach putting/longer putting one with a forehand putt, the only shot I could do and had the disc get a big chunk taken out of the disc to the point the disc would not be legal to use anymore, that and the disc flew off understable or overstable depending on what point the spin rotation would stop for the disc. I had to get new Magnet putters in Jawbreaker and Saw Disc Golf Nerd review the same disc on YouTube earlier then asked him how he like d them now, then just made the two discs 173-174 grams for my uses labeling in Sharpie one Approach as in longer putts to very short putts then the other as my putter and putting the ring from the D Magnets on the disc as I use the ring as a thumb guide when putting.
I had my old putter the one I got rid of, gone in recycling from 2007 but was one my brother tried for a month in 2004 before using a DX Gator he beat in. The other not as stiff one from 2007 was to to replace a maroon red Magnet I lost in some bushes at a tournament, maroon red is a bad color choice for a disc. So the old putters were 10 and 11 for me, as the used putter disc was only used for a month in 2004. I needed to replaced the softer hard D Magnet as I did for a few other discs that were worn out end of last year and the beginning of this year a few that were wore out and just needed replacing. I still have the old pre 2006 hard Pro D Magnet also 173-174 grams. I need to replace my uphill and downhill and well as a longer putter if I can't get my longer approach Jawbraker Magnet or my hard Pro D Magnet to work as that old one is too light a wight to really use an older Upshot #2 or U-2 as it says on the disc in Prostyle plastic, was 166 grams and is now more like 164 grams.
